Study of hybrid silicon quantum dot frequency comb laser dynamic for 5G and datacom applications

Abstract : This work reports on the high performance of a 1.3 µm hybrid quantum dot frequency comb laser. The material parameters such as gain, differential gain, and linewidth enhancement factor are studied and linked to the comb dynamics. In particular, results show that a larger linewidth enhancement factor is more beneficial for comb operation; moreover, we demonstrate that, by employing optical injection, both the 3-dB bandwidth and the flatness of the whole optical frequency comb is improved. Such novel findings give promising guidelines for the development of high-speed dense wavelength division multiplexing photonic integrated circuits in upcoming 5G telecommunications and datacom applications.
